You were doing your Normal Training Routine which for A Normal Human would be pretty freaking Insane but for you was Last Tuesday, and you were in the Middle of Training GER Contacted you.

GER: Master?

Y/n: What is it?

GER: An Extra Dimension force is Contacting you.

Y/n: What is it?

GER: It seems to be-

???: Me.

You then looked around to see you were in A Huge Tower filled with Books, and there was A Wizard standing there.

Y/n: Huh!? Where am I!? Who are you!? Where is My Family!?

???: No Need to Threaten Young Man, I merely Borrowed you for the Time being, and For your other questions I am Yen Sid, and you are in my Magical Tower.

Yen Sid (One of the Most Powerful Magic users of all time/ He literally has the power to create worlds at the Tips of his Fingers/ He is A Very serious Man Most of the time but he can be Lax when he sees A Great deal of Potential of People/ He is also the Creator of Keyblades, Magical swords shaped like Keys)

Y/n: Then why am I here then, Smart Alec?

Yen Sid: You see one of the worlds I had Created is in Grave Danger.

Y/n: Grave Danger? A Whole world?

Yen Sid: Correct. This Particular world was one where San Francisco and Tokyo had fused together to make one Massive city, but it was Threatened because A Masked Man had stolen some Powerful Nanotech which Normally wouldn't be an issue but some Outside forces had managed to amp them, and make them stronger.

Y/n: That's Bad!

Yen Sid: Exactly, I have my suspicions but it could be someone really dangerous, but I have no evidence at the Moment. Your Job is to keep this world from changing too much because if it does Many lives can be put in grave danger.

Y/n: I see, That's pretty Bad. Can you tell my family I'll be gone for A While?

Yen Sid: They had been alerted already, and it shouldn't take too Long. Also, You should take this.

Y/n: Take what?

Yen Sid: Pull out your Hand.

You then did and saw and A Weapon appeared!

Y/n: WOAH! This Looks pretty Freaking Sweet!

Yen Sid: Yes, Indeed. I shall contact other Allies with Info to tell you soon enough. I shall send you there but be weary to prevent anything bad from Happening.

Y/n: Yes, Sir!

Yen Sid: Good, Now Good Luck, Shonen Hero.

He then Teleported you to that world.

Yen Sid: Hopefully he will be far more competent than Sora. I Respect that Kid but he's not very competent. Hopefully Aqua and Kari will send me back Information soon as well.
